he term limestone is applied to any calcareous RESOURCES sedimentary rock consisting essentially T The total resources of limestone of all of carbonates. The two most important categories and grades as per UNFC system as constituents are calcite and dolomite. Limestone on 1.4.2010 are estimated at 184,935 million tonnes, often contains magnesium carbonate, either of which 14,926 million tonnes (8%) are under as dolomite CaMg (CO ) or magnesite (MgCO ) 3 2 3 reserves category and 170,009 million tonnes (92%) mixed with calcite. It is then termed 'dolomitic' are under remaining resources category. Karnataka or 'magnesian' limestone. Limestones altered is the leading state having 28% of the total by dynamic or contact metamorphism become resources followed by Andhra Pradesh (20%), coarsely crystalline and are referred to as Rajasthan (12%), Gujarat (11%), Meghalaya (9%), 'marbles' and 'crystalline limestones'. Other Chhattisgarh (5%) and remaining 15% by other common varieties of limestones are 'marl', states. Gradewise, cement grade has leading share 'oolite' (oolitic limestone), shelly limestone, of about 69% followed by SMS & BF grades (12%) algal limestone, coral limestone, pisolitic and chemical grade (3%). Remaining 16% are others, limestone, crinoidal limestone, travertine, onyx, not-known and unclassified grades (Table-1 (A)). hydraulic limestone, lithographic limestone, etc. However, the limestone which is used by The total resources of chalk of all cate- industries in bulk quantity is a bedded type gories and grades as per UNFC system as on 1.4.2010 sedimentary limestone. Other calcareous are estimated in Gujarat at 4.92 million tonnes of material used by industry is 'chalk', a white, which 4.33 million tonnes (88%) are under reserves extremely fine-grained, usually soft and friable category and 0.59 million tonnes (12%) are under variety of limestone, composed wholly or remaining resources category (Table-1 (B)). largely of microscopic small remains of The total resources of marl of all categories and foraminifera and broken shelly fragments; grades as per UNFC system as on 1.4.2010 are 'kankar', irregular nodules and concretions of estimated in Gujarat State at 151.68 million tonnes impure calcium carbonate of all sizes found in of which 139.98 million tonnes (92%) are under the older surface alluvium or soils; and reserves category and 11.70 million tonnes (8%) are 'limeshell', the thick calcareous shells of under remaining resources category Table- 1 (C). molluscs deposited in the form of beds as well as present in ancient lakes and shallow EXPLORATION & DEVELOPMENT seas.
